He underwent the latest procedure, considered a “clean up,” in July, the Daily News reported.

Stoudemire was limited to 29 games in the 2012-13 regular season, averaging 14.2 points and five rebounds. He eventually returned to play restricted minutes in four playoff games.

The Knicks used the 30-year-old Stoudemire in a reserve role, and it’s unclear whether he’ll be given a chance to start again with the additions of Andrea Bargnani and Metta World Peace.

“I haven’t made that decision. I’ll have the summer to kind of evaluate where I go with that, but I think first things first, he’s got to come back healthy,” coach Mike Woodson said in May. “I mean, that is the major part of this. Our struggles in terms of where we wanted to go this season was the fact that we had the injury with STAT. STAT was ready I thought when he came in, but he got hurt.

“A lot is going to depend on where he is once he steps foot in vet camp in terms of where he is health-wise and minute restrictions, that may be the case. All of that’s going to play a major role in STAT in terms of where we go with our ballclub and him playing, because I just don’t know at this point.”

Stoudemire signed a five-year deal worth nearly $100 million in 2010. He has two years and around $45 remaining on his contract.

The deal is uninsured due to Stoudemire’s history of knee woes, according to the Daily News.
